World of Warcraft was once a simple, fun game where everyone was on the same playing level. Now, however, players can get an instant and unfair advantage over each other by paying real money for in game gold and characters. If you want to play the game just for fun, and you don’t want to spend money on anything, then you’ll be at a major disadvantage.

Another point is that dupes, hacks and exploits have caused inflation in the game, so that gold is worth less than it once was. This is due to the huge oversupply of gold in the game and because of Chinese gold farmers who play the game all day and sell it to other players. 

Still, if you don’t want to buy gold and you just play for enjoyment, the game can still be fun. You may still want to search for some WoW Tips first, though.
